塑料焊接原理

塑料材料的厚度對超聲波焊接有影響嗎？

超声波焊接对于一切热熔性的塑料制品都可以进行焊接，而且焊接的效果好。那么如果産品材料的厚度不一样，超声波焊接出来的效果是否能一致呢？産品材料厚度薄对超声波焊接有哪些影響？其實如果塑料制品都比較薄的話，利用超聲波焊接常常會出現擊穿、變形、燙傷、壓不住等情況。

擊穿。超聲波焊接薄塑料不能整面複合，往往是焊接四周，但是常會出現中間部位被擊穿，這時我們設計超聲波焊接頭時需要將中間掏空，使非焊接部位不直接接觸到焊接頭。

燙傷。薄片的支撑力弱，超声波焊接瞬间发力可能会烫伤産品外观，可以适用超声波专用保护膜防燙傷。

焊接受损

變形。超声波焊接塑料是需要气压（0.3-0.7mpa），塑料件太薄会支撑不住，导致压接部位变形坍塌，可以重新设计産品，在焊接部位做加强筋结构。

壓不住。超聲波焊接薄塑料制品時，不能用太大的壓力，可以選擇高頻焊接，並增加焊接時間，同時，在底模工裝想辦法（全包住塑料件）。

‘Oh, yes, you could. Now do just as I tell you, Alice. When you’ve eaten, we’ll talk again.’ "Not a sign of a sign! And yet I'll swear it! Do you know where she's gone?" "Go along with your doctor," said Maitrank now, in great good humour. "If you will have the goodness to call a cab I will get back to my hotel." "I am...." “Bad news?” Larry asked, climbing to the turf. Larry braced himself against the slap of the wheels into the surface water. That might offer just enough resistance to nose them in. However, it ended, as soon as Mr. Everdail had sailed on the yacht to join his wife at their lakeside camp in Maine, uncanny light, odd noises and other strange things had become evident again, as an excited local correspondent had notified the paper. Reporters, searching, and watching, had found nothing so far but the public would be informed as soon as they discovered the secret. He believed that he had no ties now, that friendships, the love of woman, and the kiss of children all had missed him, and that his, thenceforth, must be but vain regret. So far as he knew, Felipa had gone away without ever having received his letter. The man he had intrusted it to had been killed in the Aravaypa Ca?on: that he was certain of; and it never entered his head that his papers might have fallen into other hands, and the note have finally been delivered to her. She was leading the sort of life that would most quickly put him entirely out of her mind. He was taking the Washington papers, and he knew. She had gone away, not even sure that he had given her a thought since the night in the Sierra Blanca when Black River had roared through the stillness, and they had been alone in all the wild world. What a weird, mysterious, unearthly scene it had been, quite outside the probabilities of anything he had imagined or contemplated for a single minute. He had never regretted it, though. He believed in impulses, particularly his own. Yet she not only loved Cairness as much as ever, but more. Her church had the strong hold of superstition upon her, but she might have thrown it off, grown reckless of enforced conventions, and have gone to him, had not faithfulness and gratitude held her yet more powerfully. "Yes, that is she; glad to see you back, Missy," said the General, patting the cow on the back. "Take her back and give her a good feed, if you can find it, for probably she's pretty hungry." Have you never heard of AMP burning them, you silly damn fool? Her young face bowed to his neck, and suddenly his lips crept round and lay against the coolness of her cheek. She did not move, and he still walked on, the grass splashing under his feet, the rabbits scampering round him, showing their little cotton-tails in the dark.
